Description (partial)

Symptom:
This software defect results in two symptoms:
1. In a VMware host environment, when using an active/active round-robin load balancing configuration among multiple SSRs, the user may encounter corruption of VMDK redo logs during linked clone creation. The corruption is isolated to the metadata regions of the redo log and does not affect the source of the clone. Without intervention by VMware support, these VMs will not be able to be started and in some cases may not be able to be deleted.
2. In a VMware host environment, when using an active/active round-robin load balancing configuration among multiple SSRs, the user may encounter logical corruption of VMDKs for VMs that are being migrated onto the array with Storage vMotion. This corruption may lie dormant and not be detected until a filesystem check, e.g., fsck or chkdsk is run from the guest operating system. The probability of this condition is directly related to the number of simultaneous vMotion events that are happening at once.
Conditions:
Affected platforms:
Cisco UCS Invicta Scaling Systems running version 5.0.1 of Invicta OS
WHIPTAIL Invicta running versions 4.3 or 4.5 of Racerunner OS
Active/Active round-robin load balancing configuration among multiple SSRs.
